Soil Carbon and Microbial Data from Qilian Mountains Wetlands Under Flooding Regimes

A 25.0 KB dataset on figshare by Weibo Shen, last updated in 2026, analyzes soil organic carbon accumulation mechanisms in glacier meltwater-fed wetlands. It compares soil properties, microbial necromass carbon, and extracellular polymeric substances across three anaerobic flooding gradients: non-flooding, wet-dry alternation, and long-term flooding in the 0-60 cm soil layer. The research highlights differential microbial adaptation strategies driving carbon sequestration potential in alpine wetlands.

Use Cases

• Modeling soil carbon sequestration potential based on microbial necromass carbon and extracellular polymeric substances data.
• Comparing microbial community adaptation strategies under different hydrological stresses like wet-dry alternation and long-term flooding.
• Analyzing the relationship between soil physical/chemical properties and carbon allocation pathways in alpine wetland environments.

Strengths

• Includes specific quantitative measurements, such as a reported 3.60 g·kg⁻¹ of microbial necromass carbon in subsoil under wet-dry alternation.
• Reports concrete findings like 326.21 mg·kg⁻¹ of extracellular polymeric substances under long-term flooding conditions.
• Data is structured for analysis in XLS format and is shared under a permissive MIT license.

Limitations

• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 25.0 KB, indicating a limited scope of observations.
